This from what Timothy said in another post
“Start somewhere - either blank or someone else’s. Run that on a target dummy for 2 minutes to get a baseline. Run a two minute sim of an unbuffed run to compare to. Make 1 change run for two minutes and compare. Make 1 change run for two minutes and compare etc. after about 120-200 hours of doing so you will have your macro tuned to where you want it to be. There are no short cuts - if you want the results you have to do the work.”
